DEVICE FOR TRANSMITTING MOTION.

SPECIFICATION Vforming part of Letters Patent No. 437,717, dated October 7, 1890.

Application filed J une 12, 1890.

To a/ZZ whom it may concern:

Be it known that I, CHARLIE AUGUs'r PALMQUIST, a citizen of the United States, residing at Spokane Falls, in the county of Spokane and State of Vashington, have invented a new and useful Device for Transmitting Motion, of which the following is a specification.

This invention relates to devices for trans- Initting motion; and it has for its object to construct a device of this class which shall be especially adapted to be used in places where there is not sufficient room for gear wheels of the size and strength that are really needed, such as is the case, for instance, in windmills for transmitting power from the wind-Wheel shaft to the machinery that is to be driven.

The invention consists in combining with the large gear-wheel mounted upon the main shaft a pair of supplemental shafts crossing each other and carrying bracing-wheels of which those at one end of the cross-shafts mesh with the main gear-wheel, while those at the other end of said cross-shafts mesh with a pinion upon the shaft that is to be driven, said pinion meshing also with the main gearwheel. The purpose of this arrangement is to brace the pinion upon the shaft that is to be driven and to prevent danger of accident.

The invention consists, specifically, in the improved construction and arrangement of parts which are to be hereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure l is a perspective view showing my invention applied to the turn-table of a windmill. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is a bottom view. Fig. 4 is a vertical transverse sectional view taken on the line 4 4 in Fig. 2.

Like numerals of reference indicate like parts in all the figures.

l designates the turn-table, in which is journaled the wind-wheel shaft 2.

3 designates the master-gear, which is secured upon the wind-wheel axle 2.

4 and 5 designate two shafts, which are journaled in suitable bearings in the turntable. These shafts cross each other,as shown, at a point above the wind-wheel shaft 2, the shaft 4 being arranged somewhat in rear of semi No. 355,237. (No model.)

the shaft 5. The upper ends of the shafts 4 and 5 carry spur-'wheels G and 7, both of which are in mesh with the Inaster-gear. The lower ends of the said shafts 4 and 5 carry spurwheels 8 and 9, which are out of mesh with the master-gear, the position of the shafts 4 and 5 heilig slightly inclined in a downward and rearward direction. The spur-wheels 6 and S 'at the ends of the shaft 4 are of equal size and are larger than the spur-wheels 7 and 9 at the ends of the shaft 5. These differences in the sizes of the spur-wheels is necessary for the reason that in crossing the shafts 4 and 5 it becomes necessary to arrange the one in rear of and at a greater distance from the master-gear than the other. Again, it isnecessary to cross the shafts in order to cause the several spur-wheels to arrange themselves at the proper angle or in the proper position with relation to the mastereear.

10 designates the vertical drive-shaft, which is journaled in suitable bearings inthe windmill tower. Said drive-shaft, which Inay form the pivot of the turn-table, is provided near its upper end with a pinion l1, which is arranged between the master-gear and the pulleys 8 and 9, with all of which it is in mesh.

The operation of this invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. When the master-gear rotates, it communicates motion directly to the pinion 11 upon the shaft l0. At the same time the master-gear transmits Inotion directly to the pinions 6 and 7 upon the cross-shafts 4 and 5, the pinions S and 9 at the lower ends of which also mesh with the pinion 1l. It will thus be seen that the latter receives motion simultaneously from three sources, the motion of the master-gear being communicated IOO breakage of one or more cogs of the pinion 11 it is almost certain that a portion of the uninjured rim of said pinion will at all times be in mesh with one of the three sources from which it derives its motion. I

My improved device for transmitting motion has in the foregoing been described as being applied to awindmill; but it is obvious that it may be made available in many kinds of machinery with or Without the presence of a turn-table, which latter is no essential part of the invention, but has been herein shown merely for purposes of illustration. In lieu of the said turn-table any suitable bearingblock might be employed. Such being the case, I desire it to be understood that Ido not limit myself to the precise construction and arrangement of details herein set forth, but reserve the right to any changes and modifications in the general struct-ure which may be resorted to without departing from the spirit of my invention.

Having thus described my invention, I claiml. In a device for transmitting motion, the

. combination of a master-gear, pinions mounted upon shafts, which latter are driven from lss the said mastergear, and a pinion mounted upon a shaft through which motion is to be transmitted from the master-gear to the machinery which is to be driven, said latter pinion being arranged between and in mesh with the master-gear and the pinions upon the shafts driven from said master-gear, substantially as set forth.

2. In a device for transmitting motion, the combination of a master-gear, a pinion mounted upon the shaft through which motion is to be transmitted from said master-gear to the inachinery which is to be driven, and 'supplemental pinions meshing with the said pinion and driven directly from the master-gear, substantially as set forth.

3. The combination of the master-gear, the crossed shafts provided with pinions at their upper ends meshing with said master-gear, the supplemental pinions at the lower ends of said cross-shafts, said supplemental pinions being out of mesh with the master-gear, and the pinion arranged between and meshing with said supplemental pinions and themastergear and mounted securely upon the shaft' through which motion is to be transmitted from the master-gear to the machinery which is to be driven, substantially as set forth.

4. In a device for transmitting motion, the combination of the master-gear mounted upon a suitable shaft, the shafts crossing each other above the shaft of the master-gear, one of said cross-shafts being arranged in rear of the other, the pinions at the upper ends of said cross-shafts meshing with the master-gear, the pinions at the lower ends of said shafts out of mesh with the master-gear, the shaft for transmitting motion from the master-gear to the machinery to be driven, and a pinion secured upon said shaft and arranged between and in mesh with the master-gear and lthe supplemental pinions at the lower ends of the cross-shafts, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two Witnesses.
